Anti-popping zipper with guide piece

Abstract

The invention discloses an anti-popping zipper with a guide piece. The zipper comprises a zipper left loop, a zipper right loop and a double-tooth zipper head, wherein a pull column is arranged on the double-tooth zipper head, a guide piece is fixed at the middle portion of the pull column, and the guide piece and the pull column are molded in a whole. Lower left layer teeth and upper left layer teeth are respectively fixed on the lower edge and the upper edge of a left-side cotton tape, and the lower left layer teeth and the upper left layer teeth are clamped with each other to form a left groove. Upper right layer teeth and lower right layer teeth are respectively fixed on the upper edge and the lower edge of a right-side cotton tape, and the upper right layer teeth and the lower right layer teeth are clamped with each other to form a right groove. The left portion of the guide piece is matched with the left groove, and the right portion of the guide piece is matched with the right groove. The direction of the lower left layer teeth and the direction of the upper left layer teeth are of inverse design, and the direction of the lower right layer teeth and the direction of the upper right layer teeth are also of inverse design. According to the anti-popping zipper with the guide piece, the left portion of the guide piece and the right portion of the guide piece are matched with the left groove and the right groove, and thus the correct and smooth motion between the double-tooth zipper head and the zipper left loop and between the double-tooth zipper head and the right loop. Meanwhile, the directions of the teeth are of inverse design, accordingly the function gap between the teeth is small, and therefore the zipper is difficult to tear apart.

Description

technical field [0001] The invention relates to a zipper, in particular to an explosion-proof zipper with a guide piece. Background technique [0002] Bags are used to load clothes, luggage and other daily necessities in our daily life, especially in travel, and the closure function of the zipper of the bag is very important. The frequency of repeated opening and closing of the zipper of the bag is high, which makes the zipper easy to wear and tear, especially in the process of handling. The strength of the zipper is high, and the damage and bursting of the zipper will lead to the loss or theft of the belongings in the bag. For the above-mentioned problems, the applicant has applied for a patent No. ZL201110002230.8 on 2011.01.06, which is called a patent for an explosion-proof zipper with a guide piece. [0003] The explosion-proof zipper includes: a left loop of the zipper, a right loop of the zipper and a double-tooth zipper puller. The left loop of the zipper is compose...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patents effectively solve the defects that the zipper is easy to be damaged and torn, and it is easy to explode and not durable during transportation. When this kind of explosion-proof zipper with a guide piece still has the following problems: the double-tooth zipper head and the lower left tooth and the lower right tooth The movement of the double-tooth zipper head is achieved by the combination of the upper left teeth and the upper right teeth. However, after long-term use of this structure, the double-tooth zipper head and each tooth will be stuck, resulting in damage to the zipper. In addition, after long-term use, the gap between the bottom plate and the cover plate will become larger, which will directly cause the double-tooth zipper pull to fall from the left loop of the zipper and the right loop of the zipper
